The note is a disaster for me when it comes to charging.
If your battery is low and you start charging it but using it at the same time, it doesn't get worse, but it doesn't get better either i.e. actually charge the thing, it just holds its own.
I have got to say I am not impressed with this!
I am not facing such problems. Charging takes pretty long yes but not as bad as you said. A larger battery will of course need a longer time to charge. But I wonder sometimes too if it's the battery problem or the charger output problem and if there's a way to speed up the process.

I think it is more to do with the actual charger, seems like a trickle charge or something.
Yes if charging and using at the same time you would not expect it to charge as quick, but mine doesnt really charge at all, just stays the same.
My acer iconia will charge like lightning even when i am using it, smaller battery or not it still charges!
This was one of the things i was looking forward to with the note, but this slow charge seems to make it more or less the same as what I am used to.
I have the usb plug which comes with the kindle, might it do a better job?
If anyone manages to find a proprietary charger which can produce better charging I will like to know too
That is common the charging is very slow and if you are playing HD games then the charging is almost in negative. May be its because of the voltage of the charger inputs and it is to low. Samsung must have done it for a reason may be its because of the proprietry port or the battery itself we do not know but we need to live it
Agreed, charging this thing takes a long time. Keep in mind that the battery is 7000 mAh and the charger is most likely a 2 amp charger, pegging the charge time at around 4 hours with no other losses. So if you're using it, it should take even longer.

No such issue here. I charge to full capacity while using all the time.
I get what he's saying. Because it draws so much power when you're using it; having it charging at the same time doesn't move the needle much. For example, if you're watching a movie while it's charging you'll probably be at the same point battery wise when the movies over. People complain about this all the time when their using their devices as a GPS. In some cases not only doesn't it charge but it actually continues to drain so you're worse off from where you started. We're using 21st century toys powered by 20th century battery technology.

This is a better way of saying what I mean, thank you.
I also have to say one thing I do not like doing is turning the screen brightness down. After all we all get these things as they look so good, so I am not going to make it look worse when I am using it, what would be the point in that? Its a bit like saying yeah my battery life is 14 days but actually it is on standby for that time lol...
Anyway, I still believe it should be better and the primary cause is the weak charger for what ever reason sammy decided to make it that way, but its not a good thing.
It seems like I remember someone recommending a charger that was more powerful so the note would charge faster. Can anyone confirm this?
What a fail thread. If you know ANYTHING about charging, you would know why this happens and why this is NORMAL.
But why even search or educate oneself, let's post a thread on XDA and whine a bit.
It could be worse. It takes six hours to charge a N10.
I dont face this problem i charge mine when surfing the wep
On a slightly related side note, doesn't it suck that the brightness just turns down completely when the battery is low?
The zslower charge rate protects the batteries life ,reduces the possibilty of heat and battery damage trickling insures a full charge
if you don't want your screen to dim don't use the power saving setting.
Sent using Tapatalk2 from my Note 10.1; the choice of Royalty
For all those facing the slight unresponsive screen please change the source of power, I had mine connected to UPS power supply as soon as I changed and connected it direclty the problem was gone.
Even if you read the user manual of Samsung Note its says thats one of the reasons
How Manhattan hours per day do you use the note? With a 10hrs battery life I find an overnight charge is sufficient

Wow! many friends?
Anyway moving on.. so i just got my note 10.1 about a week ago, loving it but saw that while plugged in it was not charging at all while i was using the tablet and never quite getting to 100% overnight. By not charging while using, i mean to say that it was actually discharging. Yes of course i am using the stock charger and cable.. and even stock note.
so just tried something silly. Unplugged and plugged the usb from the block repeatedly about 5 times. Now its not only recognizing and charging, but charging relatively quickly even while using. To test, i unplugged for about 20 min and plugged back in. Same great results.
Just thought i would share instead of hoarding my new found knowledge like others..
Quick update: it charged about 10% in 20 min.. Nice
I don't charge mine - I paid cash for it

It seems common behavior on the Nexus. My NS got up to 105° F last night (to be fair, it was under my pillow). I've simply taken to turning it off when I charge at night, but seeing as my NS is a glorified PMP (and therefore I don't have to worry about texts or other notifications on it), you might feel differently about simply turning it off.
Sent from my Nexus S using XDA App
It's interesting to note that the adapter for the Nexus S actually charges at(and I'm sure I'm getting my terminology wrong, sorry electricity guys!) .7AMP vs the 1AMP that other smart phones charges at such as the Nexus One.
This might account for the seemingly longer charge times we've had reported, and why you might be seeing increased heating from using a third-party more generalized charger. Whether or not there's any truth to the idea that it may cause permanent damage to your device, I don't know. I would greatly appreciate it if someone more knowledgable about this kind of thing would post, as I'm considering buying a second charger/car charger. In any which case, I personally take what Best Buy/T-Mobile/anyone's first level support tell me with a great big grain of salt.
google maps heating phone up
I just had a similar experience with my Nexus S getting really warm while using Google Maps this morning. I usually use Google Maps in Car Mode with traffic overlayed as I drive to and from work (~30-40 min. drive). This morning I noticed the phone got really warm by the end of my commute, which did not happen the previous 3 or 4 times I have used Maps in this same fashion. I will take nxt's advice and check the temperature on the phone next time it heats up again. Does anyone know what is a "safe" upper temperature limit for the phone or battery? I've read that higher temperatures are detrimental to the life of a lithium battery.
Other than this one time, I have not experienced any other high temperature issues with my Nexus S in the ~1 week that I've had it.
Thanks ahead of time for any help/advice. This is my very first smartphone and I am eagerly trying to absorb as much information as I can about it so I can determine what is normal/abnormal behavior. I am loving my Nexus S so far!
I don't think third party chargers are to blame. In fact, I'd go as far as to say the opposite is true. I read that the shorter data pins on the official charger cause the device to enter a faster charging state, as compared to the usb cable or third party chargers.
I've yet to feel my nexus s get warm at all... during charging w/ wifi on. Using samsung wall charger, using LG wall charger, using computers w/usb cable.
My NS gets hotter to the touch than my Vibrant ever did, but when I check the battery temperature it is never as high as my Vibrant used to get.
When charging in the car and running Navigation + streaming music the Vibrant would hit almost 125F whereas my NS tops out at 110F.

it depends on the usage
when i download TONS of stuff via 3G or WiFi it heats up a lot, only if i have it plugged in to the charger, else it does not heat up
However! if you check carefully, or better yet, if you take out the back cover
you will notice it is not the battery that is hot, but the area beneath the SIM card that is hot, which points to be the CPU

I see, thanks. Will keep in mind.
FWIW, I have been charging my Nexus S with the Nexus One charger (1 amp) since day 1 - I can't stand how short the stock charging cable and wall adapter were. I haven't had any unusual temperature spikes when charging at all. I don't even really notice it getting warm under heavy load - unlike the Nexus One with the aluminum casing that conducted heat very well. Edit: I also leave WiFi on with a No Sleep policy when I am at home and I've not encountered any warming issues either.
I would be careful if I ware you.. high heat is dangerous for the battery, it might swallow and even a leak if you will keep using your device constantly at high temperatures.
I Have never had any problems with heat and I have been using it a lot.
btw, I use stock rom..
Hello!
This is my first post here on the forums. I had a question about my tablet and dock... is it ok to keep them charged (above 80 percent throughout the day?). The battery just doesn't go down, and it's a force of habit to just charge it when I go to sleep. Will the battery life potential decrease over time? Should I let it run out every time I charge it?
Thanks

Tell me about it i'd get about 32hrs of use out of both Tab and Dock! but i charge it up every chance i get, i can't see it doing any harm.
I believe that's a bad habit, it's better to charge when u think u r gonna use it for next 6 hours even when the battery is still above 50%.
I know its meant to be bad habit charging when you don't need it but I wonder how much of that is true anymore and how much is just legacy from the old tech?
I know the new batteries don't suffer as much these days with over charging and they don't discharge like they used to. The actual devices have gotten better as well by stopping charge when they detect the battery is full.
So where does the legacy / rumor end and the truth begin? Its one thing to say "best practice is to fully charge & discharge" but unless you charge when you can you might run out of power without proper planning
It's old tech, these days the chargers themselves regulate the current to the battery dynamically anyways so you can keep it plugged in all you want. The only reason they tell you to drain it/charge it fully once in a while is for Android battery calibration, not because the battery will die.

I think that rumor has existed for long time. I still remember the first time I bought my laptop around 2005. this battery issue came into my consideration. searched here n there and I came into conclusion that my new laptop should adopt the 'stop charging when its full '. but I regret that, my laptop battery life drop fast less than one year.
and till now, I never want to take that risk again on my laptop, phone, n epad. well one thing for sure someone have to prove it, I hope you can report back in 6 month

Pretty informative article about lithium batteries, which is what's in the tf.
Basically, partial charge is better than full charge. Do not run the battery dry though, very bad for lithium batteries to be discharged too much. The adapter does sense a full charge and will stop, so no worries about overcharging or thermal runaway.

Specifically, it's lithium polymer, which is this article:
http://batteryuniversity.com/learn/article/the_li_polymer_battery_substance_or_hype
However yes, for most intents and purposes, li-poly behaves similarly to standard li-ion.
Partial charge is only better than full charge if the manufacturer hasn't set the cut-off point when charging *below* full charge already, though. That, only ASUS really knows so far.
Hi people... i think that Samsung has got a little of troubles of making batteries and charging philosophies.
I has got two devices that are the last technology from samsung, the nexus s and the galaxy s2 right now.
The nexus s has got a very strange trouble (until now not fixed) that battery never reach full 100% state in charging. And much very very long charging time.
The Galaxy S2 reach 100% but takes too much time to charge. It's possibile that never one has think about modifying this?
Where we can start to mod this ? Inside the kernel? Inside bootloader?
I think it's not only a mine trouble
i think its the battery charger not the phone, which makes it so slow

Mine finishes very quickly. about 1-2 hours when it's at 25 percent. And you cant fix charging. Remember that it is a big battery.
Ever tried using an adaptor for a device that has a lower rating than the adaptor? Ever heard that pop and the smell that follows?
Learn to be patient. Last thing you need is for the battery to blow up and destroy your phone.
protip: turn off your phone while you're charging with AC and not USB.
it could be your USB (and by extension, your PC) is not providing enough power to the USB ports. It happens.
My phone charges in 4 hours with AC when the phone is off. 5 when on.
6 hours on USB, phone off. 8 phone on.
It can be "fixed" in the kernel.
Samsung made it charge slower so that it charges better.
Faster charging = more heat = more dissipation, and potentially other problems.
Even though its a safety feature, its ridiculously slow. Phones takes AGES for a full charge.
these new phone are strange
my old i8910 HD charges full in like 30 min
and stays without a charge for 3+ days
Mine charges slower than htc but no too slow.. I'd say 2.5 hours full charge

Do you guys not get more than 3-4 hours of sleep?
Do you guys exhaust the battery to the point where the phone turns itself off before plugging it in?
Can you not plug your phone in before you go to bed?
I always plug my phone in before I go to bed (usually with 10-20% remaining) and I don't remember a time where I wake up in the morning and the phone isn't 100%.
I'm not trying to be cynical...just curious what other people's routines are when 3-4 hours to charge a phone becomes an issue.
A complaint like this wouldn't even cross my mind.
I need a faster charge too. Not because I'm impatient but because the phone can use more current then it can charge, especially during car navigation.

I know it helped with the old nickel cadmium batteries, but I've been under the impression that conditioning doesn't do anything with today's lithium ion batteries, that they are as good as they will get right out of the box.
Charge time Is a lot less than 8 hours normally. That said, it is still a slow charging phone compared to my previous few phones. However it is not too bad to be a complaint from me. We also have to be aware that the battery is a little bigger than the previous generation of phones, so it would take longer to charge anyway.

Yes this is using the supplied charger. Did a little searching online and it seems that there are others who have this issue. It was noted in the Anantech review as well as the following quote from the Droid Life review:
On a related note, the One takes forever to fully charge. I’m not sure why that is, but no matter what charger I seemed to grab when needing some juice, I found myself checking the status of the battery meter far more often than on other phones in my possession.

My phone needs about 4h to completely charge.
From Anandtech, the rationale is that Qualcomms fast charging is disabled in an effort to preserve the integrity of the battery's longevity; since you know, its sealed and has a repairability rating of 0. The Gs4 will probably crank that fast charge up and the user can replace the batteries as often as he deems necessary.
slow charging time seems a pretty fair trade off for a slow discharging time also right?

Maybe they designed it so that the user would be discouraged to fully charge the phone, and thus completing fewer cycles?
If it's just the last ten percent that takes such a long time, I'm not too worried about it. There are few situations during the day that I'd have to charge the phone to 100%, other than an overnight charge.

It's a pretty big batter, to start. But you're probably not getting much current to the phone. If you charge from the USB on a computer, you're hardly getting any current to the phone so it's going to charge very slowly.
The faster chargers are 2A chargers. I have a 2A car charger that came with my Nexus One car dock I've been using for a long time and it's the fastest charger I've seen out of all of them. All of my phones (and friends' phones) have charged must faster with that charger.
I have a 1.5A AC charger too. It's still not as fast as my 2A car charger, but I'm also inside at that point, so it doesn't matter. But most chargers I've seen are 1A or less. Those are slow.

It's not the battery you're conditioning. It's the battery stats on the phone. The phone needs to "get to know" the battery to accurately describe its status.
Charge time should be a tad under 4 hours on AC, so I would say something appears to be wrong. Unless of course you're doing something heavy on battery) gaming/navigation) during charging.
what scm_crash said. pick up a 2A charger if you really need juice fast, otherwise it's probably designed to simply charge overnight for longevity
I always use my nexus 7 charger (2A) when i need juice on the spot.
It's ridiculous that people here think that the HTC one is not reparable ,so HTC designed a phone that can't be open ? What if you break your screen ? So instead of repairing your screen and be charged 180 $€£ for example ,HTC will charge you 599 for a new phone cause the phone is unreparable? That's ridiculous.HTC made the phone,HTC knows how to open the phone ,HTC will put phone back together again period.

actually it's not comparable coz the volume of the battery aren't the same.
you can also check the charger's specs , a 2300mha battery charged by a 1A charger, that's approximately 2.7 hrs.
still, for the first time it took more than half an hour to charge from 99% to 100% and the LED to turn green, that was strange. probably because I deleted the battery stat file for calibration

I no longer have to worry about battery charge thanks to this new fast charge thing. 45 mins after having a low battery I'm at 80%... thank god battery charging has finally progressed to this.

Thank you to samsung and the note 4 for FINALLY putting a phone out there that is awesome!!

I agree but I rather swap my battery. When I get down to lets say 5% I don't have to worry about plugging it in. It takes less than a minute to go from 0% to 100% and it's less strain on the charging port and circuit. Plus if you still want to use the phone you don't have to be tethered to a cable.
+1 I love it. Swapping out the batter. LOL Not so much.
Battery swapping really sucks if you have a case on the phone. I vote for fast charging. Beautiful thing! I just need to get a fast car charger and I can charge my phone fully during my commute to work.
...and it's less strain on the charging port and circuit...

As an electrical engineer, seeing statements like this makes me cringe. I can absolutely assure you that there is no "strain" on the charging circuit, or battery, or anything else for that matter.
The only thing I could say is, possibly, the reduced battery life span due to the additional charge cycles. But charge cycles for modern Li-ion is already really high. But even if I were to entertain the fact that the battery might need to be replaced sooner, who cares. You are buying another battery NOW, vs the possibility of buying another battery in a year or so.
As far as personal preference goes, if a spare battery is your thing, go for it. But please try not to perpetuate the idea that the fast charging circuit or battery can't handle the charging.
I'm more than happy to go over the physics and electrical theory on how charging works. You might be interested to know that in a lab setting we can get charging rates as fast as 1 minute per 1000mAh with minimal heat build up (the major hurdle in improving charging rates)
Fast charging is nothing new. A similar concept are large capacitors, like a camera flash. They charge in seconds. The major engineering challenge is controlling the discharge rate, in most cases the heat build up is limiting factor.
Don't be surprised if the note 5 charges in 0 to 100 in less than 5 min.
Fast Charging + Killer battery life = One Happy Customer

i love everything about this post, btw. i'd love to know the physics and electrical theory if you ever want to share. it would probably help me to understand which is better for the phone, not that i need it right now, but i'm sure it would be beneficial to have that knowledge. i am one that is a fan of the fast charging, but i've also been looking at Samsung's spare battery charger too. the Korean Note 4 variants actually came WITH the spare battery charger (lucky ducks) but it's going for $45 ish right now on Samsung's website. might not be a bad investment at all, even though my battery life is averaging 12 - 15 hours on a singe charge.

This is true. I had an Energizer battery charger that could charge my AA or AAA batteries in 15 minutes. They got very hot though. This was in the 90's.

I had something like this as well. Mine had a fan on it that would attempt to keep things cool. I have an Ego lawn mower that can charge the HUGE battery pack that goes in it up by 50% in 15 minutes, and it sits on a big charging base with a huge, loud fan. That's a little different than charging a cell phone battery or AA/AAA batteries.
+1 on the fast charge thing. To me, that's revolutionary.
Fast charging is awesome, but I really don't use it. My battery life is so great the it easily lasts me the whole day with moderate usage. I usually end the day with 30+% left. The fast charging is an awesome feature, but i really have no use for it.
Someone was saying having fast charging checked depletes battery quicker. Ain't that some bs?
Has anyone given any numbers as to how slow / the rate of wireless charging is on this phone? I love fast charging but I want wireless charging as well.
I agree with a couple of these posts. I have moderate use on my phone and usually end the day at 40% or higher. However, I love having spare batteries that I can just pop in and be at 100%. Just ordered 3 plus wall charger for $20 shipped. Hard to beat having 3 full charges at hand if you don't have a chance to plug in for a while.
Battery life is great on this phone........period!!!

I believe most wireless chargers are 1 amp output. The stock wall charger is 2 amp so I'm guessing it would take about 2 1/2 to 3 1/2 hours to fully charge on wireless,I'm not expert though.

I do not doubt the usefulness of it, and I know it will come in handy some days. It's just my normals days I have battery to spare.
